Fleabane, annual (Erigeron annuus)

Winter annual broadleaf

A winter annual or sometimes biennial reaching 1 to 2 feet in height with prominent white and yellow flowers. Annual fleabane is primarily a weed of abandoned fields, pastures or no-till cropping systems and closely resembles horseweed or marestail. Basal rosette leaves are similar to but usually much wider than those of horseweed while upper leaves become more lanceolate in outline along the flowering stem. All leaves are toothed and contain hairs.
